5PCS 6MM 1/4" LED Indicator Light, AC/DC 12-24V Waterproof IP66 Metal Signal Lamp, Metal Indicator with 145mm Wire, Automotive LED Indicator Light for Cars Trucks Boats (Green)

Works well

Nice led, used on 24v supply.

Just what I needed for a little project I was working on. Now I know for sure that there is power getting to the boat bilge pump.

Just what I wanted. Fit my application perfect. Looks and works great!

My application is aboard my sailboat, specifically in the cooling-fan circuit of my air-cooled fridge-freezer. It’s easy enough to determine the cooling fan is running when the ambient noise level is low, but I wanted to be able to determine that the refrigeration unit was properly cycling even when the ambient noise levels are high, as when the auxiliary engine is running, or the wind and sea conditions get sporty. This little blue indicator is wired into the cooling-fan circuit for an easy visual indicator. For that purpose, it’s perfect.

They actually are AC or DC. I bought them as indicator lights for a HVAC system, where the signal wires run on 24VAC. I was not optimistic that the LED's would actually work on AC, but to my surprise they do. No flickering or dimness.

Nice little lights. Plenty bright & good quality

These BLUE LEDs are bright, but not too bright. I like that they come with gaskets you can install to make them water tight. They also have leads already installed. They install in a 1/4" hole - just drill, insert, fasten with the included nuts, and connect to your project. They operate on 10-15 volts DC, not 120 volts AC. I would buy these, again.
